The question given below contains three elements. These elements may or may not have some inter linkage. Each group of elements may fit into one of these diagrams at (A), (B), (C), (D) and/or (E). You have to indicate the group of elements which correctly fits into the diagrams. Which of the following diagrams indicates the best relation between Mercury, Zinc and Metal ?

Show answer & explanation
Concept: In a classification Venn diagram, when two items both belong to one broader category but are themselves distinct from each other (nothing is both at once), the diagram must show two separate, non-overlapping circles for the two items, with both of those circles lying completely inside one larger circle for the broader category. Overlapping circles would mean the two items share common members; two circles with no larger circle around them would drop the shared-category relationship altogether; and concentric (nested) circles would mean one item is a subtype of the other.
Application: Mercury and Zinc are both metals, so both need a place inside a larger circle for "Metal". At the same time, mercury and zinc are different substances - nothing is simultaneously mercury and zinc - so their own circles must not touch or overlap each other. The diagram that has one large outer circle enclosing two separate, non-touching circles captures exactly this: both are metals, and yet the two remain entirely distinct from one another.
Cross-check against the other diagrams:
Two intersecting circles would wrongly suggest mercury and zinc share some common members, which they do not.
Two separate circles drawn with no larger circle enclosing them would drop the fact that both are metals.
Three concentric (nested) circles would wrongly suggest one of mercury or zinc is a subtype of the other, rather than the two being peer subsets of metal.
